Detailed Description

In view of the above technical problems, the present disclosure provides a vehicle-mounted camera module, of which the height of the camera 13 can be adjusted. As shown in the upper part of fig. 1, in the first state, the camera 13 is lower than the interior mirror 3 of the vehicle, so that the camera 13 can take an image of a person in the vehicle at a preferable photographing angle. As shown in the lower part of fig. 1, in the second state, the height of the camera 13 is raised, and thus, the influence of the camera 13 on the field of vision of the person in the vehicle is reduced.

The following describes an example of the vehicle-mounted camera module provided in the embodiment of the present disclosure:

as shown in fig. 2 to 12, the in-vehicle camera module 1 includes a support 11, a height adjustment mechanism 12, and a camera 13. The support 11 is intended to be fixed to the roof of the cabin of the vehicle, and the camera 13 is connected to the support 11 by means of a height adjustment mechanism 12, the height adjustment mechanism 12 being intended to effect the switching of the camera 13 between the first and the second state. In the first state, the height of the camera 13 is lower than that in the second state, and in the first state, the camera 13 is lower than the interior mirror 3 of the vehicle.

Wherein the support 11 is used for supporting the height adjustment mechanism 12 and the camera 13. The cabin may also be referred to as a passenger cabin.

The height adjustment mechanism 12 is used to realize state switching of the camera 13. The height adjusting mechanism 12 may be used to switch the state by driving the camera 13 to slide, or may be used to switch the state by driving the camera 13 to rotate, which is not limited in the embodiment of the present disclosure.

The camera 13 is in a first state available for capturing images, which may also be referred to as capturing state or working state. The camera 13 may not be used to capture images in the second state, and the second state may also be referred to as a stored state or a non-operating state. The camera 13 may be a camera of a camera-monitor system (cms) for vehicles.

According to the technical scheme provided by the embodiment of the disclosure, the supporting piece 11 is fixed at the top of the cabin, and the camera 13 is connected with the supporting piece 11 through the height adjusting mechanism 12, so that when the camera 13 is required to be used for shooting, the camera 13 can be switched to the first state (as shown in the upper part of fig. 1) through the height adjusting mechanism 12, and because the camera 13 is lower than the inner rearview mirror 3 of the vehicle in the first state, the shooting angle of the camera 13 is better, and high-quality in-vehicle personnel images can be obtained.

When the camera 13 is not needed, the camera 13 can be switched to the second state (as shown in the lower part of fig. 1) through the height adjusting mechanism 12, so that the height of the camera 13 is raised, and the influence of the vehicle-mounted camera module 1 on the field of vision of people in the vehicle can be reduced.

Next, the support 11 is exemplarily described:

the mounting position of the support 11 is not limited in the embodiments of the present disclosure, and in some examples, as shown in fig. 2 to 12, the support 11 is used to be fixed to a side of the inner rear view mirror 3 facing away from the mirror surface.

Since the height adjusting mechanism 12 and the camera 13 are provided to the support 11, the entire in-vehicle camera module 1 can be located on the side of the inside rear view mirror 3 facing away from the mirror surface. Like this, interior rear-view mirror 3 has played the shielding effect to on-vehicle camera module 1 to, reduced on-vehicle camera module 1's setting and to the influence of in-vehicle personnel's field of vision.

The presently disclosed embodiments are not limited to the components at the top of the cabin for mounting the support 11, and in some examples, as shown in fig. 2-7, the support 11 is for securing to the mirror rod 31 of the interior rear view mirror 3. In other examples, as shown in fig. 8-12, the support 11 is intended to be fixed to the front windscreen 2 of the vehicle.

The embodiment of the present disclosure is not limited to the mounting manner of the support 11, and in some examples, the support 11 is fixed by a screw. For example, as shown in fig. 2 to 7, the support 11 is fixed to the mirror rod 31 of the inner mirror 3 by a screw. As another example, as shown in fig. 10 to 12, the supporting member 11 is fixed to the front windshield 2 by screws.

In other examples, the support 11 is adhesively secured. For example, as shown in fig. 8 and 9, the support 11 is bonded to the front windshield 2. For another example, the support 11 may be glued to the mirror lever 31 of the inner mirror 3.

The disclosed embodiments are not limited in the form of the support 11, and in some examples, as shown in fig. 2-12, the support 11 includes a housing having a cavity for housing the height adjustment mechanism 12 and the camera 13. In this case, the support 11 plays a role of supporting the height adjusting mechanism 12 and the camera 13, and also plays a role of protecting the height adjusting mechanism 12 and the camera 13 and a role of shielding.

Illustratively, in the first state, the camera 13 is located outside the housing. In the second state, the camera 13 is located inside the housing.

Of course, in other examples, the support 11 may also be a bracket. For this case, if it is necessary to shade the height adjustment mechanism 12 and the camera 13, this can be achieved by an interior trim of the cabin roof of the vehicle.

Next, the posture, position, and the like of the camera 13 in the first state and the second state are exemplarily described:

in some examples, as shown in fig. 1-12, in the first state, the camera 13 is oriented toward the rear of the vehicle, so that the camera 13 can better obtain images of personnel in the vehicle.

In other examples, the orientation of the camera 13 in the first state may be adjusted according to the needs of the in-vehicle personnel, e.g., the in-vehicle personnel may change the orientation of the camera 13, thereby meeting different shooting needs of the in-vehicle personnel. For example, in the first state, the camera 13 may also be oriented in front of the vehicle, so that the shooting requirements of the vehicle front by the person in the vehicle are fulfilled.

The height of the camera 13 is not limited in the first state in the embodiments of the present disclosure, and in some examples, in order to improve the photographing effect, the camera 13 is flush with the eye ellipse in the first state.

The fact that the camera 13 is flush with the eye ellipse may mean that the center point of the camera 13 is located at the same height as the center point of the eye ellipse, or that the height of the center point of the camera 13 is located between the maximum height and the minimum height of the eye ellipse, which is not particularly limited in the embodiment of the present disclosure.

To achieve that the camera 13 is flush with the eye ellipse in the first state, in some examples the difference between the height of the interior mirror 3 and the height of the camera 13 in the first state is less than 100mm. That is, the size of the camera 13 protruding from the interior mirror 3 is less than 100mm.

Illustratively, in the first state, the height of the endoscope 3 differs from the height of the camera 13 by more than 20mm and less than 50mm.

Further exemplary, in the first state, the difference between the height of the interior mirror 3 and the height of the camera 13 is more than 30mm and less than 40mm, for example, may be 35mm.

It should be noted that, as shown in fig. 2, the difference between the height of the inner mirror 3 and the height of the camera 13 may be defined as the distance between the center point of the camera 13 and the lowest point of the inner mirror 3, i.e. h1, and may be defined as the distance between the lowest point of the camera 13 and the lowest point of the inner mirror 3, i.e. h2, which is not particularly limited in the embodiment of the disclosure.

In addition, in the case where the support 11 is located on the side of the inner mirror 3 facing away from the mirror surface, in some examples, as shown in fig. 2 and 3, the camera 13 protrudes toward the rear of the vehicle in the first state relative to the second state.

That is, the camera 13 approaches toward the rear of the vehicle (toward the inside rear view mirror 3) in the horizontal direction in addition to descending in the vertical direction in the process of switching from the second state to the first state.

In this way, the distance between the camera 13 and the inside mirror 3 in the first state can be reduced, and the shielding of the field of view of the camera 13 by the inside mirror 3 can be reduced. On the other hand, as shown in fig. 4, two cameras 13 having the same height but different horizontal positions are shown, and it can be seen from the figure that the field of view of the camera 13 near the rear of the vehicle is less blocked by the inside rear view mirror 3, so that a larger angle of view can be achieved by the above arrangement.

On the other hand, as shown in fig. 5, the positions of the two cameras 13 having the same angle of view are shown, and as can be seen from the figure, the two cameras 13 have the same angle of view, but the height of the camera 13 near the rear of the vehicle is higher than the height of the camera 13 far from the rear of the vehicle, so that the amount of projection of the camera 13 with respect to the inside rear view mirror 3 is reduced, and the shielding of the view of the person in the vehicle by the camera 13 is reduced.

In summary, by providing the camera 13 to protrude toward the rear of the vehicle in the first state relative to the second state, a larger angle of view can be achieved while maintaining a certain height of the camera 13, and the amount of protrusion of the camera 13 relative to the interior mirror 3 (i.e., raising the camera 13) can be reduced while maintaining a certain angle of view of the camera 13.

To achieve a large field angle of the camera 13, in some examples, as shown in fig. 2 and 3, in the first state the camera 13 is located below the interior rear view mirror 3.

The lower part may be a right lower part or an inclined lower part (as shown in fig. 2 and 3). The camera 13 is located below the interior mirror 3, and it may be defined that there is a partial overlap of the projections of the camera 13 and the interior mirror 3 in the vertical direction.

Of course, the specific position of the camera 13 needs to be determined according to the specific scene and the actual requirement of the in-vehicle personnel for the angle of view, and in other examples, in the first state, the camera 13 may also be located on the side of the interior mirror 3 facing away from the mirror surface.

For the second state, since the camera 13 is not used to capture an image, in order to protect the privacy of the person in the vehicle, in some examples, in the second state, the camera 13 is blocked.

The fact that the camera 13 is blocked means that the camera 13 cannot capture a complete image of the person in the vehicle, for example, the person in the vehicle cannot be captured at all, or the face of the person in the vehicle cannot be captured.

The implementation manner in which the camera 13 is blocked is not limited by the embodiment of the present disclosure, and the blocking of the camera 13 may be implemented by any component. In some examples, as shown in fig. 2-12, in the second state, the camera 13 is shielded by the support 11. In other examples, the camera 13 may also be obscured by the interior mirror 3, or by the cabin, etc.

Of course, in other examples, it is also possible to limit the orientation of the camera 13 in the second state, so that the camera 13 cannot capture a complete image of the person in the vehicle. For example, in the second state, the camera 13 is not directed to the rear of the vehicle, and may be directed directly above or directly below, for example.

In addition, in the second state, the camera 13 can be in a hidden state, so that the camera 13 is not easy to be perceived by in-car personnel, and the riding experience of the in-car personnel is improved. Wherein, the camera 13 being in a hidden state means that the camera 13 cannot be observed by a person in the vehicle.

The implementation of the embodiment of the present disclosure in the hidden state of the camera 13 is not limited, and in some examples, the camera 13 is hidden on the side of the inner rear view mirror 3 facing away from the mirror surface.

Illustratively, in the second state, the camera 13 is higher than the interior rear view mirror 3, or the camera 13 is flush with the interior rear view mirror 3. Thus, the inner mirror 3 can completely shield the camera 13.

Still further exemplary, in the second state, as shown in fig. 2-12, the camera 13 is hidden inside the support 11.

The embodiment of the present disclosure is not limited to the implementation of the height adjustment mechanism 12, and the following is exemplified:

the height adjusting mechanism 12 can be realized in the following ways according to the movement form of the camera 13:

(1) In some examples, as shown in fig. 2-7, the height adjustment mechanism 12 includes a camera mount 121 and a driving mechanism 122, the camera mount 121 is slidably connected to the support 11, the driving mechanism 122 is respectively connected to the support 11 and the camera mount 121, and the driving mechanism 122 is used to drive the camera mount 121 to slide. The camera 13 is fixed to the camera mount 121.

That is, the camera 13 is switched between the first state and the second state in a sliding motion.

In some examples, as shown in fig. 2-7, the support 11 has a rail 111 and the camera mount 121 has a slider 1211, the slider 1211 being slidably coupled to the rail 111.

The sliding direction of the camera mount 121 (the camera 13) is not limited in the embodiments of the present disclosure, and in some examples, as shown in fig. 2 to 5, the sliding direction of the camera mount 121 is inclined with respect to the vertical direction, and the camera 13 gradually slides toward the rear of the vehicle in the process of sliding the camera 13 from the second state to the first state.

In this way, it is possible to achieve that the camera 13 protrudes toward the rear of the vehicle in the first state relative to the second state. Thus, the shielding of the field of view of the camera 13 by the inner mirror 3 in the first state can be reduced, and a large angle of view of the camera 13 can be ensured.

In some examples, as shown in fig. 3, the included angle (i.e., < a) of the sliding direction of the camera mount 121 with respect to the vertical direction is greater than 15 ° and less than 45 °. For example, 28 °.

Of course, in other examples, as shown in fig. 6 and 7, the sliding direction of the camera mount 121 may be a vertical direction, and the camera 13 may be capable of being lifted in the vertical direction, which is not particularly limited in the embodiment of the present disclosure.

The embodiments of the present disclosure are not limited to the implementation of the drive mechanism 122, and in some examples, the drive mechanism 122 is an electric drive mechanism for driving the camera mount 121 up and down.

As illustrated in fig. 2 and 6, the driving mechanism 122 includes a motor 1221 and a lifting mechanism 1222, and the motor 1221 is fixed to the support 11 and connected to the camera mount 121 through the lifting mechanism 1222. The motor 1221 can drive the camera mount 121 up and down by the up-down mechanism 1222.

The disclosed embodiments do not limit the type of lift mechanism 1222, and in some examples, as shown in fig. 2 and 6, lift mechanism 1222 is a lead screw nut mechanism including a lead screw 12221 and a nut 12222, the lead screw 12221 being in driving connection with the motor 1221 and parallel to the sliding direction of camera mount 121. The nut 12222 is fixed to the camera mount 121, and is engaged with the screw 12221.

When the motor 1221 rotates, the screw 12221 rotates, and the drive nut 12222 and the camera mount 121 slide along the screw 12221. By changing the rotation direction of the motor 1221, the sliding direction of the nut 12222 and the camera mount 121 can be changed, and further, the lifting and lowering of the camera mount 121 can be realized.

The screw nut mechanism may be a common screw nut mechanism or a ball screw mechanism with higher precision, which is not limited in the embodiments of the present disclosure.

In other examples, the lift mechanism 1222 is a rack and pinion mechanism including a rack and pinion, the rack being fixed to the camera mount 121 and parallel to the sliding direction of the camera mount 121. The motor 1221 is in geared connection with the gear and the gear is meshed with the rack.

When the motor 1221 rotates, the gear rotates, and the rack and the camera mount 121 are driven to slide. By changing the rotation direction of the motor 1221, the sliding direction of the rack and the camera mount 121 can be changed, and further, the lifting and lowering of the camera mount 121 can be realized.

Next, a procedure of switching the camera 13 between the first state and the second state will be exemplarily described with reference to fig. 2 and 6:

when it is not necessary to use the camera 13, if the camera 13 is currently in the first state (as shown in the upper part of fig. 2 and 6), the motor 1221 rotates in the first direction, and the motor 1221 drives the camera mount 121 to slide upward by the elevating mechanism 1222 until the camera 13 is switched to the second state (as shown in the lower part of fig. 2 and 6).

When the camera 13 is required to be used, the motor 1221 rotates in the second direction, and the motor 1221 drives the camera mount 121 to slide downward by the elevating mechanism 1222 until the camera 13 is switched to the first state.

In addition to the electric drive mechanism, in other examples, the drive mechanism 122 may be an elastic drive mechanism that is only used to drive the downward sliding of the camera mount 121, and the upward sliding force of the camera mount 121 needs to be provided by an in-vehicle person.

As illustrated in fig. 3 and 7, the driving mechanism 122 includes an elastic member 1223, and both ends of the elastic member 1223 respectively abut the supporting member 11 and the camera mounting member 121. The support 11 has a first latch 112 and the camera mount 121 has a second latch 1212.

The first lock catch 112 and the second lock catch 1212 are located opposite to each other and are used for locking in cooperation with each other, so that the camera mounting member 121 (the camera 13) can be stabilized in the second state. Also, the first lock catch 112 and the second lock catch 1212 can be unlocked so that the elastic member 1223 can drive the camera mount 121 and the camera 13 to switch to the first state.

In some examples, the first and second latches 112 and 1212 are configured to unlock when the camera mount 121 is pressed in the latched state. And when the camera mount 121 is pressed in the unlocked state, the first lock catch 112 and the second lock catch 1212 are locked.

For example, to achieve the above-mentioned functions, the first lock catch 112 and the second lock catch 1212 may be selected from a rebound device, a push button, a reset device, a latch, a heart-shaped slot structure (also referred to as a labyrinth mechanism), a hook, and the like.

Next, a procedure of switching the camera 13 between the first state and the second state will be exemplarily described with reference to fig. 3 and 7:

when the camera 13 is not required to be used, if the camera 13 is currently in the first state (as shown in the upper part of fig. 3 and 7), an in-vehicle person presses the camera mount 121 such that the camera mount 121 slides upward, the camera mount 121 pushes the elastic member 1223 to compress until the first lock catch 112 and the second lock catch 1212 are locked, and the camera 13 is switched to the second state (as shown in the lower part of fig. 3 and 7).

When the camera 13 is required to be used, the in-vehicle person presses the camera mounting member 121 again, the first lock catch 112 and the second lock catch 1212 are unlocked, and the elastic member 1223 drives the camera 13 to slide down to the first state.

(2) In some examples, as shown in fig. 8 and 9, the height adjustment mechanism 12 includes a camera mount 121 and a driving mechanism 122, the camera mount 121 being connected to the support 11 through the driving mechanism 122, the driving mechanism 122 being for driving the camera mount 121 to rotate. The camera 13 is fixed to the camera mount 121.

That is, the camera 13 is switched between the first state and the second state in a rotational movement.

In some examples, as shown in fig. 8 and 9, the camera mount 121 has a first end connected to the drive mechanism 122 and a second end connected to the camera 13. And, the second end of the camera mount 121 is close to the inner mirror 3 with respect to the first end.

The embodiments of the present disclosure are not limited to the implementation of the drive mechanism 122, and in some examples, the drive mechanism 122 is an electric drive mechanism for effecting the downward rotation and downward rotation of the camera mount 121.

As shown in fig. 8, the driving mechanism 122 includes a motor 1221, the motor 1221 is fixed to the supporting member 11, and the rotation shaft 12211 of the motor 1221 is fixedly connected to the camera mounting member 121. The motor 1221 can realize bidirectional rotation of the camera 13 by changing the rotation direction of the rotation shaft 12211.

Next, a procedure of switching the camera 13 between the first state and the second state will be exemplarily described with reference to fig. 8:

when the camera 13 is not required to be used, if the camera 13 is currently in the first state (as shown in the upper part of fig. 8), the motor 1221 drives the camera mount 121 to rotate upward until the camera 13 is switched to the second state (as shown in the lower part of fig. 8).

When the camera 13 is required to be used, the motor 1221 drives the camera mount 121 to rotate downward until the camera 13 is switched to the first state.

In addition to the electric drive mechanism, in other examples, the drive mechanism 122 may be an elastic drive mechanism that is only used to drive the camera mount 121 to rotate downward, and the force with which the camera mount 121 rotates upward is required to be provided by an in-vehicle person.

Illustratively, as shown in FIG. 9, the drive mechanism 122 includes a spindle 12211 and a torsion spring 1224. The camera mounting part 121 is rotationally connected with the supporting part 11 through a rotating shaft 12211, the torsion spring 1224 is sleeved on the rotating shaft 12211 in a ring mode, and the two torsion arms respectively prop against the supporting part 11 and the camera mounting part 121. The support 11 has a first latch 112 and the camera mount 121 has a second latch 1212.

Next, a procedure of switching the camera 13 between the first state and the second state will be exemplarily described with reference to fig. 9:

when the camera 13 is not required to be used, if the camera 13 is currently in the first state (as shown in the upper part of fig. 9), an in-vehicle person presses the camera mount 121 so that the camera mount 121 rotates upward, and the camera mount 121 pushes the torsion spring 1224 to store energy until the first lock catch 112 and the second lock catch 1212 are locked, and the camera 13 is switched to the second state (as shown in the lower part of fig. 9).

When the camera 13 is required to be used, the in-vehicle person presses the camera mounting member 121 again, the first lock catch 112 and the second lock catch 1212 are unlocked, and the torsion spring 1224 drives the camera 13 to rotate to the first state.

(3) In some examples, as shown in fig. 10-12, the height adjustment mechanism 12 includes a camera mount 121, a first drive mechanism 122a, a second drive mechanism 122b, and a link 123. The camera 13 is fixed to the camera mount 121. The first driving mechanism 122a is disposed on the support 11 and connected to the second driving mechanism 122b through a connecting rod 123, and the first driving mechanism 122a is used for driving the connecting rod 123 to rotate. The second driving mechanism 122b is in transmission connection with the camera mounting member 121, and the second driving mechanism 122b is used for driving the camera mounting member 121 to rotate. Wherein the rotational axis of the camera mount 121 may be remote from the interior mirror 3 with respect to the rotational axis of the link 123.

In the first state, as shown in the upper part of fig. 10 and 11, the link 123 is rotated downward to the first lower target position, and the camera mount 121 is rotated downward to the second lower target position.

In the second state, as shown in the lower part of fig. 10 and 11, the link 123 is rotated upward to the first upper target position, and the camera mount 121 is rotated upward to the second upper target position.

The technical solution provided in the embodiment of the present disclosure sets two-stage rotational movement such that the stroke of the camera 13 is jointly implemented by the rotation of the connecting rod 123 and the rotation of the camera mounting member 121, whereas for the solution in which only one-stage rotational movement is set, the stroke of the camera 13 is implemented by the rotation of the camera mounting member 121 only.

It can be understood that, on the premise of realizing the same stroke of the camera 13, the length of the camera mounting member 121 in the two-stage rotation movement can be smaller than that of the camera mounting member 121 in the one-stage rotation movement, and the dimensions of the connecting rod 123 and the camera mounting member 121 in the length direction can be partially overlapped, so that the overall dimension of the vehicle-mounted camera module 1 can be reduced by setting the two-stage rotation movement, the vehicle-mounted camera module 1 is convenient to hide, and the influence of the vehicle-mounted camera module 1 on the field of vision of personnel in the vehicle is reduced.

On the other hand, as shown in fig. 12, by adjusting the rotation angles of the link 123 and the camera mount 121, the camera mount 121 and the camera 13 can be brought closer to the rear of the vehicle in the first state, and thus, the shielding of the camera 13 by the inside rear view mirror 3 can be reduced, facilitating realization of a large angle of view of the camera 13.

The implementation of the first driving mechanism 122a and the second driving mechanism 122b is not limited in the embodiments of the present disclosure, and in some examples, the first driving mechanism 122a and the second driving mechanism 122b are all electric driving mechanisms for implementing switching of the camera mount 121 from the first state to the second state and from the second state to the first state.

Illustratively, as shown in fig. 10, the first drive mechanism 122a includes a first motor 1221a and the second drive mechanism 122b includes a second motor 1221b. The first motor 1221a is fixed to the support 11, and the first shaft 12211a of the first motor 1221a is fixedly connected to the link 123. The second motor 1221b is disposed on the connecting rod 123, and the second rotating shaft 12211b of the second motor 1221b is fixedly connected to the camera mounting member 121.

Next, a procedure of switching the camera 13 between the first state and the second state will be exemplarily described with reference to fig. 10:

when the camera 13 is not required to be used, if the camera 13 is currently in the first state (e.g., the upper portion of fig. 10), the first motor 1221a drives the link 123 to rotate upward to the first upper target position (e.g., the middle portion of fig. 10). After that, the second motor 1221b drives the camera mount 121 to rotate upward to the second upper target position, and the camera 13 is switched from the first state to the second state (as the lower part of fig. 10).

In the process of switching from the first state to the second state, the second motor 1221b may first drive the camera mounting member 121 to rotate upward to the second upper target position, and then the first motor 1221a drives the connecting rod 123 to rotate upward to the first upper target position. Alternatively, the first motor 1221a and the second motor 1221b may be operated simultaneously, which is not limited by the embodiments of the present disclosure.

When it is necessary to use the camera 13, if the camera 13 is currently in the second state, the second motor 1221b drives the camera mount 121 to rotate downward to the first lower target position (e.g., the middle portion of fig. 10). After that, the first motor 1221a drives the link 123 to rotate downward to the second lower target position, and the camera 13 is switched from the second state to the first state.

In the process of switching from the second state to the first state, the first motor 1221a may drive the link 123 to rotate downward to the second lower target position, and then the second motor 1221b drives the camera mount 121 to rotate downward to the first lower target position. Alternatively, the first motor 1221a and the second motor 1221b may be operated simultaneously, which is not limited by the embodiments of the present disclosure.

In addition to the electric drive mechanism, in other examples, the first drive mechanism 122a and the second drive mechanism 122b may be elastic drive mechanisms, and then the first drive mechanism 122a and the second drive mechanism 122b are only used to drive the camera mount 121 to switch from the second state to the first state, and the force with which the camera mount 121 is switched from the first state to the second state needs to be provided by an in-vehicle person.

Illustratively, as shown in FIG. 11, the first drive mechanism 122a includes a first axle 12211a and a first torsion spring 1224a, and the second drive mechanism 122b includes a second axle 12211b and a second torsion spring 1224b. The connecting rod 123 is rotatably connected with the supporting member 11 through a first rotating shaft 12211a, the first torsion spring 1224a is sleeved on the first rotating shaft 12211a, and the two torsion arms respectively prop against the supporting member 11 and the connecting rod 123. The camera mounting part 121 is rotationally connected with the connecting rod 123 through a second rotating shaft 12211b, a second torsion spring 1224b is sleeved on the second rotating shaft 12211b in a ring mode, and two torsion arms respectively prop against the connecting rod 123 and the camera mounting part 121. The support 11 has a first latch 112, the camera mount 121 has a second latch 1212, and in a first state, the first latch 112 and the second latch 1212 are unlocked, and in a second state, the first latch 112 and the second latch 1212 are locked.

Next, a procedure of switching the camera 13 between the first state and the second state will be exemplarily described with reference to fig. 11:

when the camera 13 is not required to be used, if the camera 13 is currently in the first state (e.g., the upper portion of fig. 11), an in-vehicle person presses the camera mount 121, and the camera mount 121 drives the link 123 to rotate upward, the link 123 drives the first torsion spring 1224a to store energy until the link 123 rotates upward to the first upper target position (e.g., the middle portion of fig. 11). After that, the person in the vehicle continues to press the camera mounting member 121, and then the camera mounting member 121 drives the second torsion spring 1224b to store energy until the camera mounting member 121 rotates to the second upper target position, and then the first lock catch 112 and the second lock catch 1212 are locked, and the camera 13 is switched to the second state (as in the lower part of fig. 11).

In some examples, to achieve that when a person presses the camera mount 121 in the vehicle, the link 123 rotates around the first rotation shaft 12211a first, and then the camera mount 121 rotates around the second rotation shaft 12211b again, the elastic force of the first torsion spring 1224a is smaller than the elastic force of the second torsion spring 1224 b.

When the camera 13 needs to be used, if the camera 13 is currently in the second state, the in-vehicle person presses the camera mount 121, and the first lock catch 112 and the second lock catch 1212 are unlocked. The first torsion spring 1224a drives the link 23 to rotate downward, the second torsion spring 1224b drives the camera mount 121 to rotate downward until the link 123 rotates downward to the first lower target position, and the camera mount 121 rotates downward to the second lower target position, and the camera 13 is switched to the first state.

In some examples, in order to improve stability when the link 123 and the camera mount 121 are rotated, a guide groove may be formed in the support 11, and then the link 123 and the camera mount 121 may slide along the guide groove when they are rotated.

In addition to the above classification according to the movement form of the camera 13, the height adjustment mechanism 12 may be classified into an electric height adjustment mechanism 12 and a manual height adjustment mechanism 12 according to the power source, and the following are respectively exemplified:

(1) In some examples, the height adjustment mechanism 12 is motorized, and the height adjustment mechanism 12 is configured to drive the camera 13 from the first state to the second state, and from the second state to the first state.

Illustratively, the height adjustment mechanism 12 includes at least a motor 1221 (or a first motor 1221a and a second motor 1221 b) and a camera mount 121, and the motor 1221 is capable of achieving state switching of the camera 13 by driving the camera mount 121. Wherein fig. 2, 6, 8 and 10 illustrate a specific implementation of the motorized height adjustment mechanism 12.

For the electric height adjusting mechanism 12, the position of the camera 13 in the first state may be set to a fixed position or may be set to be adjustable according to the needs of the personnel in the vehicle. For example, an in-vehicle person may adjust the position of the camera 13 in the first state by controlling the magnitude of rotation of the motor 1221. In this way, the shooting angle and height of the camera 13 can meet the needs of different in-vehicle personnel.

(2) In some examples, the height adjustment mechanism 12 is manual, the height adjustment mechanism 12 being configured to drive the camera 13 from the second state to the first state, and the force with which the camera 13 is switched from the first state to the second state needs to be manually provided by an in-vehicle person.

Illustratively, the height adjustment mechanism 12 includes a resilient drive member, the support 11 has a first latch 112, and the camera mount 121 has a second latch 1212. When the camera mounting member 121 is pressed in the first state, the camera mounting member 121 drives the elastic driving member to store energy until the first lock catch 112 and the second lock catch 1212 are locked, and the camera 13 is switched to the second state. When the camera mounting member 121 is pressed in the second state, the first lock catch 112 and the second lock catch 1212 are unlocked, and the elastic driving member drives the camera mounting member 121 to drive the camera 13 to switch to the first state.

Wherein fig. 3-5, 7, 9 and 11 illustrate a specific implementation of the manual height adjustment mechanism 12. Accordingly, the elastic driving member is an elastic member 1223, a torsion spring 1224, or a first torsion spring 1224a and a second torsion spring 1224b.

The disclosed embodiments also provide a camera mounting bracket, as shown in fig. 2-12, including a support 11 and a height adjustment mechanism 12. The support 11 is for being fixed to the roof of the cabin of the vehicle, the height adjustment mechanism 12 has a camera mount 121, the camera mount 121 is for mounting the camera 13, and the height adjustment mechanism 12 is for effecting switching of the camera mount 121 between the first state and the second state. The height of the camera mount 121 in the first state is lower than that in the second state, and in the first state, the camera mount 121 is lower than the inside rear view mirror 3 of the vehicle.

According to the technical scheme provided by the embodiment of the disclosure, the camera 13 is installed by using the camera mounting bracket, so that when shooting is required, the camera mounting piece 121 can be switched to the first state by the height adjusting mechanism 12. Since the camera mount 121 is lower than the interior mirror 3 of the vehicle in the first state, the camera 13 can take a photograph at a preferable photographing angle, and a high-quality in-vehicle human image can be obtained.

When shooting is not required, the camera mounting member 121 can be switched to the second state by the height adjusting mechanism 12, and then the influence of the camera mounting bracket and the camera 13 on the field of vision of the person in the vehicle can be reduced.

In some examples, the support 11 is intended to be fixed to the side of the inner mirror 3 facing away from the mirror surface.
